There's just one thing missing from this, and possibly all sniper games: Psychological effect. I mean, picture this: You're in cover, but you're pinned down by three Nazis and their Sargent. Sure, you could pop in and out, OR you can, with a slightly trickier shot, nail the sargent right between the eyes, causing said Nazis to run the fuck away of just crawl into a corner, go foetal and suck their thumbs.
